By speed · Order from slowest to fastest.

1. A giant tortoise 500 m/h

   Giant tortoises can live over 150 years, ambling through more than a century of slow, steady days.

2. A crawling baby 1.4 km/h

   Babies often invent their own crawling styles, from the classic hands-and-knees to a one-legged commando shuffle.

3. A person jogging 10.8 km/h

   Humans are among the best endurance runners on Earth, able to outlast horses over very long distances in heat.

4. A falling raindrop 34 km/h

   Raindrops are not teardrop-shaped; they flatten into tiny hamburger buns as they fall through the air.

5. A golf ball off the driver 340 km/h

   A driven golf ball can briefly spin thousands of times a minute, which is what makes it climb and hold the air.

6. The speed of sound at sea level 1.2K km/h

   Sound travels faster in warm air than cold, so a thunderclap's timing shifts slightly with the weather.
